Rotary ignition system for a catalytically heated curling device

In a curling device having a tubular body defining a heating chamber therein, and having first and second ends and a hair winding portion disposed between the first and second ends and surrounding the heating chamber, heating means including a catalyst means disposed in the heating chamber, a housing member proximate the tubular body including fuel supply means for storing a fuel in a liquid state, and aspirating means coupled between the fuel supply means and the heating chamber for vaporizing the fuel and for mixing the vaporized fuel with air and for supplying a vaporized fuel/air mixture to said catalyst means, and self-contained ignition means mounted in the first end of the tubular body proximate the catalyst means for initiating oxidation of the vaporized fuel/air mixture in the presence of the catalyst means and including a manually rotatable member having a ring member connected to a lobed member having cam surfaces, mounted in said ignition means and having an axis of rotation substantially parallel or concomitant to the longitudinal axis of the tubular body, a friction wheel mounted in said ignition means having an axis of rotation substantially perpendicular to the longitudinal axis of the tubular body, flint means mounted in said ignition means and including a flint biased against said friction wheel wherein a predetermined rotation of said friction wheel against said flint causes a spark, the improvement comprising:

• a one-piece bushing member having a cylindrical portion disposed in a hollow interior of said lobed member and a cam follower portion and a tappet portion having a free end rigidly connected to said cam follower portion, said cam follower portion having matching cam surfaces to said cam surfaces of said lobed member, said free end of said tappet portion cooperating with said friction wheel for translating the rotary motion of said rotatable member to a rotary motion of said friction wheel, wherein said bushing member is displacable along the longitudinal axis of the ignition means.
